Abstract

Elektromekanik supap (EMS) sistemleri çok sayıda araştırmacı, motor ve otomotiv parça üreticileri tarafından geliştirilmektedir. Bu sistemler motorun tüm çalışma koşulları için supap zamanlamasında sağladığı esneklik sayesinde, potansiyel olarak motor performansını iyileştirme kabiliyetine sahiptir. EMS sistemleri, konvansiyonel kam mili sistemlerinin aksine supap zamanlamasını krank mili pozisyonundan tamamen bağımsız olarak gerçekleştirir. Bu sayede elektromekanik supap teknolojisi emme ve egsoz supaplarının açılma ve kapanma olaylarının denetimine imkân sağlayarak yakıt tüketimi ve emisyonların en aza indirilmesinde büyük bir potansiyele sahiptir. Bu çalışmanın amacı, 12V’luk besleme gerilimine sahip bir EMS sisteminin değişik supap çalışma aralığındaki dinamik performansını araştırmak ve böylece içten yanmalı bir motoru destekleme limitlerini belirlemektir.
